# Standard Normal Distribution or Z Score

A small post-production company re-masters soundtracks for movies and television shows, through a process that tries to minimize reading errors on the final master DVD copy. This population of master DVDs will have errors that are normally distributed, with a mean of µ = 3.5 errors/DVD and a standard deviation of σ = 1.75 errors / DVD.

If Screen Green Productions contracts post-production for 14 films with this company, what is the probability that Screen Green Productions will experience on average no more than 2 errors / DVD?
